Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If water-based ultraviolet-curable inks are used, then environmental and safety properties are improved, but coating film performance and strength deteriorate
Solution Approach 1:
The patent uses a composite approach by combining water-based ultraviolet-curable inks with specifically designed polymerization initiators (compounds of formula (1) containing aryl groups and metal ions) and radically polymerizable compounds. This composite system maintains the environmental benefits of water-based formulations while achieving enhanced coating film strength and performance through the synergistic interaction of these components.
Solution Approach 2:
The patent modifies the chemical parameters of the ink formulation by introducing specific polymerization initiators with defined molecular structures (formula (1) with aryl groups A1, A2 and metal ions Xm+) and controlling the particle size and concentration of radically polymerizable compounds. These parameter changes enable the water-based ink to form coatings with improved mechanical strength and durability while maintaining environmental compatibility.
